Which RAM should I install in my Acer Nitro 5 AN515-42?

So I am confused between these two rams. https://www.amazon.in/Micron-Basic-Crucial-2400MHZ-SODIMM/dp/B07PM6MWJD/ref=cm_cr_arp_d_product_top?ie=UTF8 and https://www.amazon.in/Micron-Basic-Crucial-2400MHZ-SODIMM/dp/B01BIWKP58/ref=cm_cr_arp_d_product_top?ie=UTF8&th=1. I want to know the difference between the updated one and the single rank one in order to order one. I want to add an 8 gig stick to make it run in dual channel. Why is the updated one cheaper and is it compatible with the laptop and will it give dual channel mode? I have read that it does work on the Nitro series laptops but I'm still a little sceptical and cautious because the products are non returnable. Any help will be appreciated!

Can you send some screenshots of the cpuz program?

This is one of the RAMs I am looking at. I just wanted to know whether the other RAM I linked works or not because it is an updated and cheaper option. I want to know whether it will work, if it won't, I will just go forward with this RAM.
